Get error messages when posting/viewing board

[joel2g3]

when I open a board ( general discussion ) - any board - I get an error message :

8: Undefined variable: showmods
(c:\inetpub\wwwroot\yabbse\Sources\MessageIndex.php ln 110)

Or when I try to post I get an error message:

8: Undefined index: attachment
(c:\inetpub\wwwroot\yabbse\Sources\Post.php ln 574)

Or when I try to edit my profile, I get an error message:

8: Use of undefined constant websiteurl - assumed 'websiteurl'
(c:\inetpub\wwwroot\yabbse\Sources\Profile.php ln 449)

The messages  I get are similar to each other,  what should I do??
